A spectrophotometer consists of two instruments, namely a spectrometer for producing light of any selected color (wavelength), and a photometer for measuring the intensity of light. For solutions where intensity of light is proportional to the concentration, we use spectrophotometer.

What is the difference between a QA spectroscope and a tube spectroscope?
A QA spectroscope is typically used for qualitative analysis, focusing on identifying elements in a sample. A tube spectroscope is used for quantitative analysis, measuring the intensity of spectral lines to determine concentrations of elements in a sample. Both instruments rely on the same principles of spectroscopy but differ in their applications and precision.
Why is metal used in an electroscope?
Metals are used in an electroscope because they are good conductors of electricity. This allows the electroscope to easily detect and respond to electric charges. Metal materials also provide durability and stability to the electroscope's components.
Name the kind of electroscope that can recognized to be charged just by observation?
Type your answer here... electroscope switch electroscope square
How can you tell if metal leaf electroscope is neutral or positive?
To determine if a metal leaf electroscope is neutral, bring a charged rod near the metal cap. If the metal leaves diverge, the electroscope is neutral. If the metal leaves collapse or diverge more, the electroscope is positively charged.
What if the electroscope leaves hang down?
If the leaves of an electroscope hang down, it typically indicates that the electroscope is positively charged since like charges repel each other. The excess positive charge on the electroscope causes the leaves to spread apart due to the repulsive force.

What is the difference between the telescope and a spectroscope?
telescope-is a instrument designed to gather and magnify energy of objects in space so the energy is study spectroscope-a instrument used to seprate light into very fine bands
How can you tell the difference between a positively charged object and a negativly charged object by using an electroscope?
A positively charged object will cause the leaves of the electroscope to separate or diverge. A negatively charged object will cause the leaves to come together or converge.
What is the plural of spectroscope?
The plural of spectroscope is spectroscopes.
If the leaves of and electroscope spread apart it indicates that?
the electroscope has acquired a net charge. This charge can be positive or negative, depending on the nature of the object that interacted with the electroscope. The repulsion between the like charges on the leaves causes them to spread apart, indicating the presence of a charge.
Why does the leaves of an electroscope collapse when you touch the upper part with your hands?
When you touch the upper part of an electroscope with your hands, charge is transferred from your body to the electroscope, neutralizing the charge on the leaves. This causes the repulsive force between the like charges on the leaves to decrease, allowing the leaves to collapse.
If you grounded the electroscope what does that do to the leaves of your electroscope?
...Guys...This is the answer of question...it simple! If we grounded the electroscope..whatever the charge on leaves are, positive or negative (as it depends with which charge you electrolyse the electroscope), if its positive and ground is negative (attraction) or if same + + so repultion
Can you tell if an object has a positive or negative charge with a electroscope?
Yes, an electroscope can determine if an object has a charge, but it cannot distinguish between a positive or negative charge. If the object causes the electroscope's leaves to diverge, it indicates the presence of a charge on the object. Further experiments or additional methods are required to determine the polarity of the charge.
Why do the leaves of a charged electroscope move further apart if a rod with the same charge is brought near?
When a charged rod is brought near an electroscope, the charges on the rod repel the charges in the electroscope, causing a redistribution of charge. The leaves of the electroscope will then move further apart because like charges repel each other, leading to an increase in the separation between the leaves.
What is the definition of spectroscopy?
The use of the spectroscope; investigations made with the spectroscope.
What are the types of electroscopes?
The different types of electroscopes are - i. Pith ball electroscope ii.Gold leaf electroscope iii. Needle electroscope
How can you tell that an electroscope is charged?
You can tell that an electroscope is charged by observing the divergence of the leaves. If the leaves spread apart after bringing a charged object close to the electroscope, it indicates that the electroscope has acquired a charge.
